One/Two step

You have to use _________ operations to solve equations

What is the first step to solve for b:

2b = -16

• add 2 to both sides

• subtract 2 to both sides

• multiply 2 to both sides

• divide 2 to both sides

What what is the inverse operation of subtraction?

• subtraction
• multiplication
• division

What is the inverse operation of division?

• Division
• Multiplication
• Addition
• Subtraction

To Solve the Equation Below, you'd
x - 62 = 123

• add 62 to each side
• subtract 62 from each side
• multiply each side by 62
• Add 123 to each side

• x = 20
• x = 7
• x = 10
• x = 3

• j = -7/10

• j = -34

• j = 280

• j = 6

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

• t = 20

• t = -20

• t = -40

• t = 40

What was done to solve the equation?

(Line 1) 5x - 8 = 32

(Line 2) 5x = 40

(Line 3) x = 8

• add 8 to both sides, then divide both sides by 5

• add 8 to both sides, then divide both sides by 40

• subtract 8 from both sides, then divide both sides by 5

• subtract 8 from both sides, then multiply both sides by 5
